Mainly you will find two most important variants when you go for a bet: European roulette and American roulette. Looking at these two variants we can conclude that European roulette is more popular, which has everything to do with the lower (bank) house advantage.
The cylinder of the game is fully rounded and divided into boxes that all also have colors. For example, there are black numbers, red numbers and the numbers 0 and 00 are always displayed in green.
The numbers you find in a cylinder while playing roulette always have a fixed order as described below per variant:
With regard to the cylinder and the further game appearance, you should know that with roulette the cylinder can always be found at the head of the console. Here you will find the playing field, where all kinds of different bets can be placed on the possibility of inside and outside bets. Inside bets are formed by the individual numbers you can play on and when talking about outside bets this is a bet on a series with numbers. Black and red are a good example in the latter case.
If you play live roulette at a physical establishment or an online casino, you always find the croupier (dealer) at the gaming table next to the cylinder. After all, the dealer is responsible for forming a result, which he or she will do by passing the ball in the roulette cylinder. In case of a physical game, you will of course receive chips in cash back from the dealer and if you play online your winnings will automatically be added to your balance by the software.
